The term "ANSI pipe" often refers to pipes manufactured according to standards set by the American National Standards Institute. Therefore, the full form of ANSI in this context is American National Standards Institute.
American National Standards Institute (ANSI) Explained
ANSI itself doesn't manufacture pipes. Rather, it is a private, non-profit organization that oversees the development of voluntary consensus standards for products, services, processes, systems, and personnel in the United States. This means that ANSI accredits standards-developing organizations (SDOs) that create and maintain specific pipe standards.
Key Functions of ANSI Regarding Piping Standards:
- Accreditation: ANSI accredits SDOs that develop piping standards. This ensures that the standards are developed using a fair, open, and consensus-based process.
- Coordination: ANSI coordinates U.S. standards with international standards, facilitating global trade and interoperability.
- Recognition: ANSI recognizes standards that have been developed and approved using its accredited procedures.
Examples of Piping Standards Recognized by ANSI:
Many different organizations develop pipe standards that ANSI recognizes. Here are a few examples:
- ASME (American Society of Mechanical Engineers): ASME develops standards for various piping components and systems, including pressure vessels and boilers. An example is ASME B31.3, which covers process piping.
- ASTM International (American Society for Testing and Materials): ASTM develops standards for materials used in piping systems, such as steel, plastic, and other materials. These standards specify the chemical composition, mechanical properties, and testing requirements for these materials.
- AWWA (American Water Works Association): AWWA develops standards for water and wastewater piping systems.
Therefore, when someone mentions "ANSI pipe," they usually refer to a pipe manufactured in accordance with a standard approved or recognized by ANSI, often developed by organizations like ASME or ASTM. The specific standard will dictate the pipe's dimensions, material, pressure rating, and other critical characteristics.
